Description

Whirling drain

Technical field

The invention relates to a vortex outlet with an outlet disc, into which the outlet slots are molded, to which an air guide plate is always assigned.

The state of the art

Such eddy discharges are known in a variety of shapes and embodiments. Here, reference will be made, for example, to DE-OS 40 2G 932.9. As a rule, bearing discs are used for receiving the air guide plates, for example as shown in DE-OS 33 32 052.5.

Such eddy discharges have proven to be excellent for injecting hot and / or cold air, but the amount of air to be blown into the spaces is limited by the number and size of the discharge slots.

SUMMARY OF THE INVENTION

It is an object of the present invention to further improve swirl outlets and to increase the amount of blown air.

The holes in the discharge disc are considered between and / or around the discharge slots to solve the problem.

In this way, the outlet creates a certain overpressure, so that the air does not flow only through the outlet slots, and especially also outwards openings. This means that the air flows from the entire outlet disc in different directions. considerably more air can be blown into the space through a single outlet.

It is also essential to interconnect the flow technique between the air guiding fins and the openings.

On the other hand, the guiding flows from the discharge slots into the perpendicular airflow of the air in the sub-space, in preference to the air fins, impart an air flow to the helical movement that extends from the apertures and changes its direction.

In the embodiment of the invention, the apertures are not arranged only by the knife of the discharge drain slots are located breast slits, but also around the anao orifices.

The disk is circular, the tanto ring is also circular. However, it is also conceivable that the outer ring of openings forms a cylindrical veil of air in which air can be introduced with a helical movement. In this way, particularly warm air can be blown very deeply into the space before the forced flow is terminated, the warm air is divided and rises again.

In order to achieve good and desirable air flow control, it has proven advantageous that the largest number of holes between the outlet slots are shaped with a relatively small diameter, while the holes in the ring around the outlet slots have a larger diameter. Also, the openings in the ring around the discharge slots may allow air to flow more freely into the spaces. On the other hand, the air emerging from the smaller diameter orifices is entrained in a helical movement, but draws the helical whirling air downwards into the spaces. This shows that the different air flows are effectively complementary.

Overview of the drawings

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing. This shows in plan view the swirl outlet according to the invention, Fig. 2 shows a section through the swirl outlet according to Fig. 1 along line II-II.

DETAILED DESCRIPTION OF THE INVENTION

The swirl outlet according to the invention is a discharge disc which is surrounded by a zen-arched edge strip.

according to Figures 1 and 2, its outer plow 3 bears the soda on the soroo 4 in a trycor directional direction.

First, rectangular discharge slits 5 are formed into the discharge disc. In the present embodiment, these discharge slits 5 have different lengths 1 and 1. However, all other geometric shapes, such as angular, elliptical, teardrop-like, and the like fit within the scope of the invention. It will further be appreciated that not all of the holes have the same diameter but can be shaped differently. All these shapes and shapes should be understood by the idea of the present invention.

Furthermore, it is seen in particular in figure 2, the outlet slots are allocated slats 5 T_.Přednost is given T_ slats rotatably supported on a shaft ^ 'Pťičsniž axis 3 located between the two plates ^and bearings ιθ ·

The bearing plates 9 and 10 may be cut out of the material of the disc 1 and bent upwards during the punching of the discharge slots 5. In the context of the invention, other mounting plates of the bearing plate are also possible. or 10 forms a groove 12 or 13 on both sides. In order to fix the bearing plate 9 or 10 in the discharge slot 2, the bearing plate or 10 can then be inserted and rotated into the outlet slot of the edge edge of the discharge slot 5. lamella fastening 7 and other additional spot welds and similar fastenings are not necessary.
